Solution Overview

Problem

Current treatments for Huntington's disease focus on symptom management, with no cure or prevention available, and existing therapeutic approaches face challenges in delivering agents to affected neurons in the brain.

Innovation Solution

An apheresis device using HTT binding molecules, such as antibodies specifically targeting Huntingtin protein or fragments, to capture and remove Huntingtin from the blood plasma, thereby addressing the systemic nature of the disease.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional therapeutic agents are used to target Huntingtin in the brain, then disease progression can be addressed, but delivery to affected neurons remains unsuccessful

Engineering Contradiction:
Improvedelivery effectivenessVSAvoiddelivery system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses plasma as an intermediary medium to deliver HTT binding molecules to the brain. Instead of directly injecting agents into the brain or using complex neural delivery systems, the invention circulates binding molecules through the blood plasma, allowing them to cross the blood-brain barrier and reach affected neurons naturally, thus simplifying the delivery system while improving reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention replaces complex mechanical delivery systems (such as intracranial injections, viral vectors, or nanocarriers) with a biological mechanism - the natural circulation of blood plasma. This substitution eliminates the need for invasive mechanical procedures while achieving effective delivery of therapeutic molecules to the brain

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If Huntingtin lowering strategies are implemented, then disease pathology can be addressed, but lack of delivery to targeting site prevents effectiveness

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidadministration simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention leverages the body's own circulatory system to deliver the therapeutic agent. The HTT binding molecules are administered intravenously and automatically circulate through the blood plasma to the brain, utilizing the body's natural self-service delivery mechanism rather than requiring external mechanical assistance or complex administration procedures

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The blood plasma serves multiple functions: it acts as the delivery vehicle for HTT binding molecules, provides a natural pathway across the blood-brain barrier, and enables continuous circulation to reach all affected neurons. This multi-functionality simplifies administration while ensuring reliable therapeutic delivery

Inventive Principle:
Principle #6Universality (Multi-functionality)
